6 Claims.

Thisinvention relates to improvements. in reeling devices for use incoiling thin metal as it comes from a processing mill, and has as itsprincipal objects to provide a new and improved expansible winding, drumfor a reel of theclass described, of a novel and simplified form, soarranged as to be readily expanded or collapsed in a simplified manner,when it is desired to coil the metal, or to remove the coiledmetal fromthe drum. i

,Heretofore, expansible winding drums have been commonly used forcoiling thin metal. Expansion or collapse of these drums has beeneffected by various forms of linkage arrangements or by cam or wedgeactions. These expanding mechanisms have all been relatively complicatedwith a number of wearing parts, and the effort necessary to expand orcollapse the drum, especially with the cam andwedge type mechanisms, hasbeen excessive. Due to space limitations, it has not been possible toprovide adequate bearing, area for the parts and construct them ofsufficient size to withstand these excessive pressures and wear.

In my present invention I overcome these difficulties by providing asimplified form of expanding mechanism for a winding drum for coilingmetal, which enables the parts to be of greater size and strength thanwith expansible winding drums heretofore used, and which also gains theadvantage of rolling friction of the expanding parts against the usualsliding friction between these parts which is present in the reelingdrums of this type now in use.

Other objects of my invention will appear from time to time as thefollowing specification proceeds, and with reference to the accompanyingdrawings, wherein:

Figure ,9 is a transverse sectional view taken substantially along line,9-9'of Figure 3 and Figure 10 is a transversesectional view takensubstantially along line lll .|0of Figure 8. In the embodiment. of myinvention illustrated in the drawings, the stripmetal coming from therollingmill, cleaning device or other processing mill, is wound on awinding drum I0 mounted on ashaftl I l overhanging a supportingframework I3. Said shaft is journaled in a bearing supportmember 12mounted on said supporting framework. Said bearing support member is ofa relatively heavy construction, to support said drum and shaft inoverhanging relation with respect thereto, so the coil of strip metalmay be removed from the overhanging end thereof. A suitable motor (notshown) is provided to drive said shaft and winding drum through asuitable drive connection'which may be of any well known type. 'Thestripmaterial may be propelled to the reel in a suitable mannen'such so as apair of pinch rolls, and may be formed to conform to the shapelof thereel so it may be wound thereon by means of a suitable forming means,whichmay be the usual form of belt wrapper, or a plurality of rollsarranged to bend the metal to the form of said reel in a manner wellknown to those skilled in the art. Said forming mechanism is not hereinshown or described since it forms nopart of my presentinvention.

Referring now in particular to the details of the winding drum. I0 andcertain novel features of my invention, saidwinding drum consists of a ldrum segment l5, journaled on the shaft II, and

a plurality of expansible drum segments l1, l1, pivotally connected toopposite sides of said first mentioned drum segment and forming a continuation of the periphery thereof, to provide a said drum seg generallycylindrical drum, when ments are in an expanded-position.

The drum segment l5 i provided with bearing' support members l6, [6extending inwardly from opposite ends thereof, the inner ends of whichare split in a plane extending through the center of the shaft, to forma meansfor journalingsaid drum segment on said shaft (see Figure 5).Said drum segment is likewise provided with spaced apart inwardlyprojecting portions |B,- |8, spaced inwardly from the ends thereof,which extend partially around outer rings |9, |9, of suitableanti-friction bearings for said shaft (see Figure 6) The expansibledrumsegments I1, I! are each provided with a plurality of spacedapartinwardly extending lug 20, 2|] extending inwardly from one side thereof.Said lugs are recessedwithin the bearing support members l6, l6 and theinwardly projecting portions l8, [8 of the drum Segment l5. lugs andsaid bearing support members and inwardly extending portions, to'pivotally connect said expansible drum segments to opposite sides ofthe drum segment IS, in such a manner that the outer periphery of saidexpansible drum seg-. ments and the drum segment IE will be generally inthe form of a cylinder, when said expansible drum segments are in anexpanded position.

The means for expanding the drum segments H, I! or permitting them tocollapse includes a plurality of spaced apart eccentrics 23', 23,

herein shown as being formed integral with the shaft Annular rings 24',24 encircle said eccentrics and the inner peripheries of said rings forminner races of antief riction' bearings between said eccentrics andannular rings. The bearings between said eccentrics and rings are hereinshown as being needle bearings Of a well" 'known construction andinclude a plurality of Rods 22, 22 extend through said.

hardened rollers of a small diameter'interposed between said eccentrics.andsaid rings (see Figure 6). The outer peripheries of the annular rings'24, 24 are adapted to engage spaced apart bearing shoes 26 26 on theinside of an expanding member 21. 'Said expanding member extends alongsaid winding drum for substantially the entire length thereof, and isdisposed between.

adjacent free sides of the drum segments l1, l1. oppositely facinginclined sides 28, 2B are pro vided on said expanding member which areadapted to engage inclined sides on adjacent ends of said movable drumsegments-so that rectilinear movement of said expanding member in anwhen the drum segment I5 is held from rotation and the shaft continuesto rotate, the eccentrics 23, 23 and annular rings 24, 24 will cause theexpanding member 21 to move in an outward direction and pivot saidexpansible' drum segments outwardly to an expanded condition. Saideccentrics are so arranged that 180 degrees of rotation thereof withrespect to the drum segment IE will fully expand the drum from acollapsed condition, and the same amount of rotation of said shaft withrespect to said drum will permit said drum to be fully collapsed.

Yieldable means are provided to move the ex panding member 21' inwardlytowards the center of the winding drum Ill, as the eccentrics 23', 23are moved in a direction to permit the drum segments H, H to collapse.As herein shown, said means includes a plurality of spaced apart yokes30, 30 secured to the inner side of said expanding member in asuitablemanner, such as welding. Corresponding yokes 3|, 3| are journaled on theshaft II and are connected to the yokes 3B; 30 by means ofconnectingrods 32, 32 extendin through opposite ends of said yokes. Said expandingmember is urged towards the shaft H by means of compression springs 33,33 encircling said rods and interposed between opposite outer sides ofthe yokes 3|, 3| and collars 34, 34, secured to the outer ends of saidrods. Nuts 35, 35, threaded on said rods, abut the outer sides of theyokes 30, 33, to hold said rods to said yokes and to provide a means foradjusting said springs.

The drum segments H, I! are collapsed, as the expanding member 21 movesinwardly towards the shaft II, by means of spaced apart tension springs36 and 31 (see Fi'gures 2, 3 and 7). The tension spring 36 is mounted atthe end of said drum adjacent the bearing support member I21 and hasconnection at its opposite ends with said movable drum segments,adjacent the free ends thereof (see Figure '7). The tension spring 3'!is mounted at the opposite end of said drum segments and is connectedthereto at its opposite ends, adjacent the free ends thereof (see Figure2). Said springs thus tend to hold said drum segments in engagement withthe inclined sides '28 of the expanding'member 21 and move said drumsegments to a collapsed condition as said expanding member moves towardsthe shaft II.

A clutch member 4|) is provided to drive the winding drum H) from theshaft Said clutch member is feathered on said shaft and is provided withjaws 4| and 42 at opposite sides there-.

of, either one of which may have driving en gagement with a jaw 43 onthe drum segment [5 (see Figures 3, 8, 9 and 10). The jaw 42 is of agreater depth than the jaw 4| so that when the clutch member 40 is movedaway from the drum segment I5 to disengage the jaw 4| from the jaw 43,the shaft may rotate with respect to said drum until the jaw 42 enga esthe jaw 43. The jaw 42, however, can never be moved to a position topass by the jaw 43. Rotation of i said shaft with respect to said drum,when the jaw 4| is disengaged from'the jaw 43 and said drum isheld fromrotation, as herein shown is degrees and is sufficient tocompletely'expand, or permit the drum segments ll to be completelycollapsed. It should here be noted that since thejaw 42 can never clearthe jaw 4 3, that when it is desired to collapse the drum, the directionof rotation of the shaft; "must be reversed.

A friction band 45 is provided to engage the drum segment l5 and holdsaid drum segment from rotation, when the jaw-4| is disengaged from thejaw 43. As herein shown. said friction band is secured to the supportingframework H3 at one of its ends by means of afpin 46. Said friction bandextends over the segment I5 and engages the outer peripheryof' a flangedmember 41 projecting from the end-thereof adjacent the clutch member 4!The opp site end of said friction band has connection a cable 49, whichserves to engage said band with said braking surface and hold said drumsegment from rotation. The cable 491s trained downwardly from saidfriction band, under a sheave 50, and inwardly to alever lit, to whichsaid cable is secured, A sheave 53 is mounted on a shaft 52 which alsohas: said lever mounted thereon. Said sheave is; adapted: to, rotate;said shaft and rock said lever.

member to an engaged position.

40 will be moved in a ing framework l3, and is provided with abifurcated outerend 64, which is pivotally connected to a yoke 65,pivoted to a bracket 66 projecting from said supporting framework.- Acompression spring 61 encircles said rod and is interposed betweensaidI-beam and the bifur cated end of said rod, and urges said rod in adirection to causesaid yoke to move said clutch It may be seen from theforegoing that when i the foot lever 56 is depressedQthe clutch memberposition to permit the jaw 4| to be disengagedfrom the jaw 43. At thesame time, the friction band 45 willengage the drum segment l5, to holdit from rotation. When said drum is held from rotation, the shaft llwill rotate with respect thereto until thejaw 42 engages the jaw 43.During this, time the expansible drum segments I 7, I! may be moved froma collapsed to afully expanded positionL Upon engagement of the jaw 42with the jaw 43 and the release of pressure from said foot lever, thewinding drum 10 will continue to irotate, in

the same manner as formerly. When it is desired to collapse the drumsegments l1, H, the direction of rotation of the shaft I ,l is reversedand the foot lever56. is depressed, to hold the drum segment 15 fromrotation and to disengage the jaw4l from thejaw 43. This permits theshaft II to rotate, 180 degrees with respect to the drum segment l atwhich time the jaw 42 will engage the jaw 43 and the eccentrics 23, 23and annular rings 24, 24 will have moved the expanding member adiswedge-shaped expanding member engaging adjacent ends of saidexpansible drum segments, andan operative connection between saideccentric' and expanding member. including an anti-friction bearing, theouter periphery of the outer race of which is adapted. to engage saidexpanding member. 2. In a reel for strip metal, a shaft, an expansibledrum mounted on said shaft including a drum segment journaled on saidshaftgex pansible drum segments pivotally connected-to oppositelends ofsaid firstmentioned drum segment and forming continuations thereof, andmeans for pivoting said drum segments in an outward direction, to form,a generally cylinl drical drum including an expanding member engagingadjacent ends of said movable drum segments, a member journaled on saidshaft eccentric of the center thereof and engagin said expending member,means for holding said drum from rotation, and a drive connection fromsaid shaft to said first mentioned drum segment, said drive connectionincluding means for selectively I permitting rotation of said shaft withrespect to said druma predetermined distance and rotating said shaft anddrum together beyond this distance, for causing said eccentricallymounted member to move said expanding member outwardly from the centerof said drum and pivotally move said drum segments in an outwarddirectionytoan expanded position. i 3. In a reelfor strip metal, ashaft, an expansible drum mounted on said shaft including a a drumsegment journaledon said shaft, expansible tancesufiicient to permit thetension springs 36 and 31 to fully collapse said drum segments.

It may thus be seen that a simplified form of expansible windin drum forsheet metal has been provided which is so arranged that the drum may beexpanded or collapsed through a simple form of mechanism, by simplyholding the drum segment I5 from rotation and permitting the shaft torotate 180 degrees with respect thereto, that this mechanism permits theuse of relatively large heavy parts, and that rolling friction in placeof sliding friction effects the expansion of the drum.
